. BUCKET-PUMP.

SPECIFICATION forming part of Letters Patent No. 749,836, dated January19, 1964.

Application filed January 9, 1903.

To all whom, it may concern; I

Be it known thatI, LEOAVBRIGEL, J r., a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Bucket-Pumps; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in bucket-pumps.

One of its objects is to provide a bucketpump which can be used withnarrow wells or cisterns having small openings and which will at thesame time work satisfactorily and reliably under the varying conditionsof weather, location, position, and treatment received.

Another object is to provide an improved top wheel to assist inattaining these several advantages and which shall at the same time belight, strong, not interfered with by ice, and not influenced byirregular setting of the pump.

It also consists in certain details of form, combination, andarrangement, all of which will be more fully set forth in thedescription of the accompanying drawings, in which- Figure l is asectional diagram of my improved pump. Fig. 2 is a side elevation of thetop wheel. Fig. 3 is a top plan View of Fig. 2. Fig. 4: is a section online a a of Fig. 3. Fig. 5 is a view similar to Fig. 2,showing amodification.

In pumps of this class heretofore it has been found impractical tooperate top wheels having less than eight faces, due to a variety ofcauses, among which is a tendency of the chain to climb out of itsproper position on the wheel, particularly if not set plumb on' thecurb, also due to the effect of ice in cold weather aggravating thistendency, also to the improper, irregular, or too-rapid turning of thewheel. It is found inpractice that the manufacturer is required toprovide a pump which will work well under all these adverse conditions,and in order to meet these requirements it has been necessary heretoforeto provide a large top wheel, and where narrow seen No. 138,329. (Nomodel.)

wells were encountered a small lower wheel was resorted to as a partialremedy. This, however, entailed an uneven or irregular action, due tothe difference in size between the wheelsand the difierent speeds atwhich they revolved, which also tends to make the chain. climb. I

By proper shaping and proportioning the top wheel I am enabled toprovide a wheel having only six standard faces, which has little, ifany,itendency for the chain to climb, which is not afiected byaccumulated ice, which will work satisfactorily even when the pump isnot set plumb on the curb, and which. due to its small diameter, isparticularly adapted to narrow and deep wells and to cisterns havingsmall openings and with which bucketpumps could not be heretoforesatisfactorily employed.

In Fig. l of the drawings I have shown a pump embodying my improvements,in which A represents the chain formed alternately of bucket-links B andthe flat sheet-metal links C, which are of ordinary construction. Drepresents the bottom wheel, and E the top wheel, which is turned bymeans of a crankshaft 6. The top wheel E is formed of the hub F, thespokes G, the wings or blades H, and the curved connecting-bars I. Theblades are connected to each other and to the spokes by means ofcross-bars J. The chain is guided and prevented from climbing by theengagement of the links C with the blades H, and these blades arecarefully and smoothly curved in a radial and also in a circumferentialdirection, as indicated in Figs. 2, 3, and 4, so as to engage andsmoothly and unfailingly guide the flat links to their proper positionon the wheel, so that they will rest centrally between the blades withtheir ends resting on the crossbars J. The form of the blades is suchthat any ice which may accumulate on them will be cut or scraped away bytheflat links without affecting the operation of the pump, and in casethe pump is not set plumb or the pump is turned irregularly or too fastthey will still guide the links to their places. The bars I are curvedso as not to contact with the bucketlinks, so that no wear of thebucket-links will occur and so that any ice which may accumuwhich areattached centrally to the bars I, and thereby forms a particularly lightand at the same time strong wheel. By employing either of the above topwheels I am enabled to use a smaller pump-box.

Having described my invention, what I claim is 1. In a bucket-pump, thecombination with a chain having alternate buckets and fiat links, of-atop wheel comprising spaced pairs of blades oppositely disposed one tothe other, said blades being circumferentially curved and having theiroppositely-disposed faces extending outwardly in radial convex curves,cross-bars connecting each of said pairs of blades secured at the baseof the radial curved portions thereof, and concave bars arranged betweenand connecting the blades of each of the pairs, substantially as setforth.

2. In combination with a bucket-pump and chain composed of alternateflat links and buckets, a top wheel provided with a plurality ofoppositely-disposed blades arranged in pairs upon said wheel, saidblades being curved in the direction of their length and having radialconvex curves upon their oppositely-disposed faces, cross-barsconnecting the blades of each pair and arranged at the base of theradial curved portions thereof, outwardlycurved reinforcing-ribs securedto the end blades and to said cross-bars, and concave bars connectingeach of the blades of the several pairs whereby contact of thechain-links therewith is prevented, substantially as described.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
